[Bioc-devel] S4 Method of ExpressionSet Signature Not Found

[Dario Strbenac]

Good day,

The variables have the same contents.

Browse[1]> selectParams at featureSelection
nonstandardGenericFunction for "DMDselection" defined from package "ClassifyR"

function (expression, ...) 
{
    standardGeneric("DMDselection")
}
<environment: 0x4452b00>
Methods may be defined for arguments: expression
Use  showMethods("DMDselection")  for currently available ones.
Browse[1]> getGeneric("DMDselection")
nonstandardGenericFunction for "DMDselection" defined from package "ClassifyR"

function (expression, ...) 
{
    standardGeneric("DMDselection")
}
<environment: 0xb4996c8>
Methods may be defined for arguments: expression
Use  showMethods("DMDselection")  for currently available ones.
Browse[1]> c
Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function 'DMDselection' for signature '"ExpressionSet"'

It only happens after I use :

detach("package:ClassifyR", unload = TRUE)
install.packages("ClassifyR/", repos = NULL)
library(ClassifyR)

because I'm modifying the package code and installing it repeatedly, to find a bug.
